BINDER;

Application filed December 12, 1927; Serial No. 239,537.

This invention relates to improvements in binders and has for its primary object, the provision .of asbinder for, receiving loose leaves or pages which may be removed from 5 the binder as a unit when desired and instantly bound in book form for storing away, WVlllCll leaves-the binder intact for repeated use, as certainworking parts of the b nder are recovered when the loose leaf unit'is,

l removed therefrom.

Another object of the invention resides in aloose leaf binder which includessectional posts which may he gradually built up and on which the pages are received to facilitate the accommoc'lation of the same as they are placed thereon. I i

Another object is to provide a'loose leaf binder including front and back covers, the back covers havingremovable sectional posts on which the loose leaves are placed and to which tliefront cover is removably locked, and which post-sco-act wit-h certain tubular elements which telescope the same to facilitate the removal of the loose leaves from the binder, without disturbing their alignment preparatory to the final binding of the same.

A further object is the provision of a loose leaf binder including front and baclrcovors with studs rising from the back cover and excover, and a novel form of locking device slidable over the free ends of the posts and frictionally engageable therewith to tightly clamp the leaves between the covers and which is instantly removable without the use of keys and like elements to facilitate the insertion. of additional leaves int-he binder.

A still further object is to provide a loose leaf binder which is simple of construction, easy to operate and by the use of which the temporarily bound sheets may be heldin unitending through the bound leaves andfront Figure 2 is a vertical sectional view there through.

'Referring to the'drawings by reference characters, the Figure 1 designates my loselea'f binder in its" entirety which includes a back cover 11 of rigid material and a front cover 12 of similar material. The back cover 11 is hingedly connected to a fiat tubular base strip 13 as at 14. Rivet-ed into the tubular base strip 13 atjsuitably spaced distances are collars 15each having a recess 16 therein for stud 17 which passes .therethrough beyond the inner side of the'strip and threads into a threaded bore v18 in a collar 19: having a flange 20 which rests upon the inner face of the basestrip The collars 19 serve as the bases of the posts 21 which rise therefrom and which consist of sections 22 of various len ths each being provided with athreaded socket 23 at one end and a threaded stud2 l' at its opposite end. By the use of sectional posts, any desired height of post may be built, either preparatory to applyingtheloose leaves 25 thereon, or as the thickness of the bound leaves increases. The post sections22 are joined together threading the stud -24of one section to the socket'23 of the next ad counter-sinking the square headof. a threaded jacent section, the lowermost post section having its stud 24 threaded into the bore 18 of collar 19; The post sections having socket-s or holes 26 therein for the insertion of an instrument should they be screwed together too tight to be removed by the hands of an operator. p

The loose leaves are provided with the usual spaced openings 27 for accommodating the posts when applied thereto, but before applying; the first loose-leaf over the post, an auxiliary back cover 28 is first applied and has a loose binding; flap or strip 29 pasted thereto as at 30 and folded back against the cover 28 to tie flat thereagainst. The flap later serves to bind the loose leaves when removed from between the covers 11 and 12 of the binder.

lVhen the desired amount of loose-leaves have been placed into the binders for temcover 31 is placed over the post and the front binder cover 12 next applied.

The front binder cover like the back cover 11 is hingedly connected to a tubular base strip as at and has collars 34L riveted therein in even spaced relation with the collars 15 on the base strip 13. The collars each have an internally threaded bore 35 to allow the respective post to freely pass therethrough and to threadedly receive the reduced threaded sleeve 36 of a binder friction lock 37. The lock 37 comprises a hollow casing 38 from which the sleeve 36 depends. The top of the casing is closed by a cover plate 39 having an opening therein for the v age of the post and from which a tongue 40 extends. The cover'plate is fixedly attached to the casing by any suitable means such as by sweatingor upsetting the peripheral edge of the casing thereover. A slot 4L1 provided in the side wall of the casing 38 while a locking disk 42 loosely contained within the casing has a finger 43 extending through the slotfor movement over the bottom wall of the slot which bottom wall is beveled inwardly atone end thereof as at ll. The disk 42 has a central opening 44; for the passage of the post to which the lock V is applied; The locking disk l2 is held in an unlocked position when the finger 43 is moved to a position in alignment with the tongue at) as thesaid finger rests upon the flat bottom wall of the slot and is held in a horizontal position by the linger engaging beneath the tongue. The post is free to slide lherethrough but when locking the device, the manipulating finger 43 is pushed from beneath the tongueto the beveled end of the bottom wall which allows the disk to drop to an angular position for rimming; engagement with the posters shown in Figure 2 of the drawings; The tongues 10 and fingers 43 of the two locks extend inwardly toward or outwardly from each other after the locks have been screwed tight within the collars 34s to prevent the top cover from striking the tongue and finger when the cover is swung back to an open position. After the locks have beenscrewed to their respective collars 3%, they form an integral part of the front cover section and need not be disturbed when removing the front cover section from the posts, as the lingers of the lock disks 4:2 are the only parts to be touched.

Having described the manner of binding the loose leaves in the temporary binder, I shall now proceed to explain'the manner in which the temporarily bound leaves may be removed as a unit without disturbing; their unitary arrangement. Assume that the hinder has been filled with the desired amount of loose leaf pages containing records which are to be kept for future'references. The first step is to unlock the binder locks 37 in the manner already explained whereupon. the front cover section is removed as shown in Figure 5 of the drawings. The uppermost post sections 22 are removed and tubular sleeves 45 are driven through the front aux- .iliary cover 31, through the aligned openings in the loose leaf pages until. the-sleeves telescope the uppermost remaining post sections. The sleeves have flanges 46 on their outer ends to limit insertion through the pages and each has an annular rib 17 pushed inward to tightly bind the sleeve with its respective post. The'auxiliary covers 28 and 31 and the pages interposed therebetween are now solidly bound together and it only becomes necessary to remove the back cover to free the bound'sheets of any parts of the original binder excepting a certain amount of the post sections 22. To remove the back cover,

a key 48 is inserted into each of the recesses 16 and engaged with the respective square heads of the stud 17 By turninp; the stud 1.7, the same will unthread from the collar 19 whereupon the back cover is free to be sepa rated from the bound volume.

After theremoval of the back cover, the binding strip or flap 29 is brought over the back edge of the bound volume and pasted flat against the outside of the front auxiliary .cover 31. The inner face of the strip may be provided with an adhesive substance 49 which needs only to be moistened to adhere to the back edges of the pages and to the exterior of the auxiliary front cover. The strip 29 when pasted conceals the flanges 46 of the sleeves 45 and imparts a finished book-like appearance thereto as shown in Figure 9 of the drawings. i

In order to aceomntiodate loose leaves having' openings of diderent smaller diameters, it becomes necessary to provide some means for interchangeably building posts of difi'erentdiameters. In Figure 11, I have shown a headed stud 17 similar to the stud 17 with the exception that it has a reduced threaded shank for threading engagement with the collar 19 which constitutes the base section of the post. v

In Figure 12, I have shown a slightly modified form'of anchor member 51-for use in the tubular base strips-13 and 32 in lieu of the collars 15 and 34. The member 51 is of a shape to snugly fit Within the tubular' base members and has a central opening 52 therein for co-action with either the stud 17 or sleeve 36 of the lock, depending upon the covers on which it is mounted.

\ From the foregoing description, it will.

' placement of any of the parts, except the" post sect-ions which remain in the bound-volume. However, these post sections as well as the locking sleeves 45 may be recovered when and if the bound volumes are destroyed after serving their purposes.

\Vhile I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any. Way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole ofmy invention limited only by the appended claims.
